Abstract: A light emitting user input device can include a touch sensitive portion configured to accept user input (e.g., from a user's thumb) and a light emitting portion configured to output a light pattern. The light pattern can be used to assist the user in interacting with the user input device. Examples include emulating a multi-degree-of-freedom controller, indicating scrolling or swiping actions, indicating presence of objects nearby the device, indicating receipt of notifications, assisting pairing the user input device with another device, or assisting calibrating the user input device. The light emitting user input device can be used to provide user input to a wearable device, such as, e.g., a head mounted display device.

Abstract: A method involves receiving, at a host device, information indicative of available bandwidth on a variable bandwidth connection between the host device and a display control device, which may be based on monitoring a signal level on the connection, a link radio modulation mode, traffic on the connection, or the data rate of any return signals from the display control device. The method includes setting one or more parameters used to generate the display data that change compressibility of the display data based on the information, where compressibility of the display data affects efficiency of compression of the display data, and where the setting of the parameters may be based on a compression algorithm used when compressing the display data. The method includes generating the display data using the one or more parameters, compressing the display data, and transmitting the display data to the display control device.

Abstract: Described herein are systems and methods for providing access to a database in a multi-tenant environment, including the use of a connection pool, with support for efficient repurposing of connections. In accordance with an embodiment, a software application can request that a connection be provided, to enable access to the database. In response to receiving the request, the connection pool can first determine if a particular connection with the exact desired attributes already exists within the pool, but is borrowed at the time of the request. If such a connection exists, then the connection pool can wait a period of time for that particular connection to become available, referred to herein as a double-wait. Subsequently, if the particular connection is not made available within the double-wait time period, the connection pool resumes its usual operation, for example by repurposing other connections.

Abstract: A method of generating video in three-dimensional animation environment is provided. The method includes: obtaining and translating directorial hints for making a 3D animated movie based on user input; determining camera configurations in a 3D environment according to the directorial hints; establishing a camera search space that includes multiple candidate cameras to be used at different timestamps to shoot one or more scenes of the movie based on the camera configurations; performing editing optimization based on the camera search space and the directorial hints, to obtain an edited video. The editing optimization is formalized into a process of finding a path with minimum cost in a graph model, each path describing a candidate camera sequence for producing the movie, and at least some of the directorial hints are translated into cost functions of the graph model. The edited video is output as the produced 3D animated movie.

Abstract: In example embodiments, techniques are provided for converting geometry of an infrastructure model represented as high-level geometric primitives having a given symbology to low-level primitives, and encoding these low-level primitives into tile contents suited for transmission, and ultimately display upon, on a client device. An architectural split between frontend applications and backend applications may allow conversion of the high level primitives to be performed remote from the client devices by backend applications. Backend applications may be executed on robust hardware devices that execute software in a multi-threaded environment on powerful CPUs. By performing CPU-intensive operations on backend applications, frontend applications on client devices may be required to do little more than submit low-level primitives for rendering on their GPU.

Abstract: A data location table master system generates a master data location table storing associations of tokens with storage nodes for varying responsibility levels. When the master data location table is updated, the data location table master system updates storage nodes affected by the update as well as other storage nodes and application nodes in the system. Then, the storage nodes and the application nodes store a copy of the master data location table. A token migration and synchronization process reallocates data object storage among the storage nodes based on the updated master data location table.

Abstract: A plugin can allow for tracking objects within a computer-aided design (“CAD”) application. In one example, the user can select an object or family of objects to track. The plugin can set a parameter of the tracker to match that of the selected object(s). The tracker can be joined to the selected object to form a new assembly, such as by embedding the tracker within the object. A user can define areas, such as rooms or floors, within the layout. The plugin can poll the trackers, which report which areas the corresponding object is within. The plugin can compile this information and display quantities of object types per area.

Abstract: Described augmented reality (AR) systems and devices provide users with enhanced human sensorial perceptions using digital content. More particularly, smartglasses create an immersive AR experience for visitors of cultural sites using object identification and optical flow tracking. The system software platform and methodology are especially suited to design and deploy immersive AR experiences to visitors of cultural sites on user wearable devices. Unencumbered by clumsy handheld devices, users are free to roam through augmented environments, indoors and out, without barriers allowing a story to unfold before their eyes. Cultural sites come alive, improving educational outcomes for heritage destinations. Using graphical user interfaces, the system enables platform administrators to convert disparate cultural site content to coherent AR story-telling experiences called palimpsests or tours.
